Dual-belt synchronous clamping conveying device

Abstract

The invention relates to a dual-belt synchronous clamping conveying device, and belongs to the technical field of material conveying. The device comprises an oblique frame for supporting a driving roller and a pull-down tension roller, wherein a lower layer conveying belt is wound on the driving roller and the pull-down tension roller; an upper framework and a lower framework extend out of the frame; a driven roller is further supported on the driving roller of the frame; a synchronous driving roller is supported on the upper framework; a swinging rod of which the lower end is provided with a floating roller is hinged to the upper framework; a slide rail swinging rod of which the lower end is provided with a gravity roller is hinged to the lower part of the lower framework; the upper end of a bilateral cylinder is hinged to the upper end of the lower framework; the lower end of the bilateral cylinder and the slide rail extending along the length direction of the slide rail swinging rod construct a moving pair; an upper layer conveying belt is wound on the driven roller, the synchronous driving roller and the gravity roller; the floating roller is arranged on the upper layer conveying belt. According to the dual-belt synchronous clamping conveying device, stable and continuous conveying can be realized under the condition of large inclination angle, and a material inlet can float along with a shape to adapt to the height change; moreover, an automatic tensioning mechanism is flexible and reliable, materials are prevented from falling off, and automation and centralized control are realized easily.

Description

technical field [0001] The invention relates to a conveying device, in particular to a double-belt synchronous clamping conveying device, which belongs to the technical field of material conveying. Background technique [0002] The known conveying mechanism usually consists of a conveyor belt, a driving roller, a tensioning device, a braking device and the like. The conveyor belt is looped on the driving roller, and the driving roller drives the conveyor belt to move by the friction between the driving roller and the conveyor belt. In order to increase the friction between the driving roller and the conveyor belt and ensure the stable operation of the device to avoid slipping, a tensioning device is usually used to tighten the conveyor belt to increase the pressure between the roller and the conveyor belt and increase the friction. [0003] When the traditional conveyor only relies on friction to convey, the inclination angle is only allowed in the range of 0°-20°. If you ...

Problems solved by technology

However, it is difficult for U-shaped or V-shaped belts to achieve an inclination angle of more than 30°, and the running speed will be limited due to the reduction of the loading section, and the conveying volume will be reduced.

Although the tubular tape can reach an inclination angle of more than 45°, the transportation volume is small and the cost increases

[0004] The search found that the Chinese patent application with the application number of 200710053814.1 disclosed a belt conveyor with a large inclination on the ordinary belt. This machine is equipped with ...
